At what distance to IDENTIFY and and what height for the cameras? If the height is no more than 8 feet and you want to IDENTIFY at 15 feet out, then it is a great camera provided you have light. Or it is a great overview camera. But if you want to IDENTIFY 40 feet out, it is the wrong camera.
Most here find that cameras and motion activated floodlights ends up causing problems with image exposure and are bad for surveillance cameras.. What happens is then the camera is momentarily blinded and you lose the ideal capture when the lights kick on and the camera adjusts from basically no light to a lot of light.
Motion activated lights are not a deterrent. There are enough videos here showing that perps do not flinch when a floodlight turns on. They avoid homes all lit up, so go with floodlights on all night.
Watch this video someone posted and how the floodlight comes on and they don't even flinch. But then the audio comes on and they don't know which way to run LOL.
Either keep the lights on all night or not at all to ensure the best chance of capture.
Here is usually what happens when a motion activated floodlight comes on - it just about completely blinds the camera right at the moment of optimal opportunity to get the picture. There are 3 deer in this picture and two of them are lost in the blinded white while the camera's exposure adjusts to the rapid change in available light:
Or this example that completely missed the perp:
First off, they shouldn't buy crap NVRs. Dahua NVRs' can easily export video to a thumb drive in MP4 as can Hik's. Most of the time it is simply a matter of them not taking the time to figure it out, until they need the video NOW. I've seen BI user's be guilty of doing the same. Couldn't be...

Andy's cameras are Dahua and Hikvision OEM equipment sold under the names Loryta and Empiretech. IPC is short for IP camera and isn't a brand. Every POE camera is IPC.
Some of my cameras I have bought from Andy from his Amazon and AliExpress store come as Dahua cams in Dahua boxes with Dahua logos, and some are not logo'd - I think it depends on how many cameras Andy buys if he gets them with the Dahua Logo or not. But regardless, they are Dahua units. If you get a unit that has Dahua on it, then the camera GUI will say Dahua; otherwise it will simply say IP Camera but looks identical except without the logo. Some of his cameras may come with EmpireTech stamped on them as well.
As long you you buy from the vendor EmpireTech or Loryta on Amazon (or AliExpress), they are Andy cams and Dahua or Hikvision OEM.
His cameras and NVRs are international models and many of them are not available through Dahua and Hikvision USA authorized dealers, but his cameras and NVRs are usually better than what you can find from a USA authorized dealer.
You can update the firmware on Andy's cameras and NVRs from the Dahua and Hikvision website, thus proving they are real Dahua and Hikvision. But you will find that the firmware we get from him is actually better and more recent than what is on the Dahua website because many members here provide feedback to Andy and then Dahua makes modifications to the firmware and sends back to him and then he sends out to his customers. These have been great improvements that Dahua doesn't even update their firmware and add to their website. So many of us are running a newer firmware than those that purchase Dahua cameras through professional installers. Smart IR on the 5442 series is one such improvement. Autotracking on the 49225 and 49425 PTZ is another. We got the next version of AI SMD 3.0 prior to anyone else as well.
Look at the threads here where members are actually testing firmware and improving it for Dahua - find a Dahua dealer with that type of relationship that Andy has with Dahua - I don't think you will find it. Look at the Dahua 4k camera on the 1/1.2" sensor as an example -
Dahua provides cameras to Andy to sell before Dahua even made it available and look at all the improvements being made to the firmware from input from customers right here on this site. And the kicker is, we are not Dahua's target market - it is the professional installers...
You do have to be careful with some rebranded cameras purchased from other vendors as they are cameras that are for the Chinese region but have been hacked into English but then are not able to be updated or they will brick. Buying from a reputable source is key to make sure that doesn't happen.
